CSProcess
public final class Merge2Int extends java.lang.Object implements CSProcess
Merges two strictly increasing int input streams into one strictly increasing output stream.Process Diagram

Description
Merge2Int is a process whose output stream is the ordered merging of the integers on its input streams. It assumes that each input stream is strictly increasing (i.e. with no repeats) sequence of integers. It generates a strictly increasing output stream containing all -- and only -- the numbers from its input streams (eliminating any duplicates).Channel Protocols
Input Channels in0, in1 int All channels in this package carry integers. Output Channels out int All channels in this package carry integers. Example
The following example shows how to use Merge2Int in a small program. The program also uses some of the other plugNplay processes. The program prints, in ascending order (up to Integer.MAX_VALUE), all integers whose prime factors consist only of 2, 3 and 5. Curious readers may like to reason why the infinitely buffered channels are needed.import org.jcsp.lang.*; import org.jcsp.util.ints.*; import org.jcsp.plugNplay.ints.*; public class Merge2IntExample { public static void main (String[] argv) { final One2OneChannelInt[] a = Channel.one2oneIntArray (4); final One2OneChannelInt[] b = Channel.one2oneIntArray (3, new InfiniteBufferInt ()); final One2OneChannelInt c = Channel.one2oneInt (); final One2OneChannelInt d = Channel.one2oneInt (); final One2OneChannelInt e = Channel.one2oneInt (); new Parallel ( new CSProcess[] { new MultInt (2, a[0].in (), b[0].out ()), new MultInt (3, a[1].in (), b[1].out ()), new MultInt (5, a[2].in (), b[2].out ()), new Merge2Int (b[0].in (), b[1].in (), c.out ()), new Merge2Int (c.in (), b[2].in (), d.out ()), new PrefixInt (1, d.in (), e.out ()), new DeltaInt (e.in (), Channel.getOutputArray (a)), new PrinterInt (a[3].in (), "--> ", "\n") } ).run (); } }

Merge2Int
public Merge2Int(ChannelInputInt in0, ChannelInputInt in1, ChannelOutputInt out)
Construct a new Merge2Int process with the input channels in0 and in1 and the output channel out. The ordering of the input channels makes no difference to the behaviour of this process.- Parameters:
in0
- an input channelin1
- an input channelout
- the output channel
